After Anthropic’s third-party tool restrictions priced agentic users off Claude Opus 4.6, the cheapest working OpenClaw stack is Z.ai’s $18/mo GLM 5 Turbo plan, with Ollama-cloud’s $20/mo GLM 5.1 and MiniMax’s $40/mo highspeed tier as the next two rungs. Kimi 2.6 stays API-only because local deployment needs roughly 750 GB of RAM.

Key Takeaways

• Z.ai’s $18/mo plan running GLM 5 Turbo is the cheapest OpenClaw backend that actually works.
• MiniMax highspeed at $40/mo handles heavier workloads without the four-figure surprise bills.
• Kimi 2.6 needs around 750 GB of RAM to self-host, so almost everyone runs it through the API.
• Keep Claude on the planner role; route scheduled jobs to the cheap backends.
• China-hosted models trade dollars for privacy on iMessage, contacts, and email skills.

Why $1,500/mo Opus Bills Pushed Users to GLM

The pressure here is simple. The moment Anthropic’s third-party tool restrictions kicked in, OpenClaw users who had been running on the Claude Pro CLI got nudged onto pay-per-token API access. At Opus 4.6 list pricing of $15 per million input tokens and $75 per million output tokens, agentic loops add up fast. The OP of the r/openclaw PSA thread tracked his own bill at roughly $1,500/mo before he switched. That figure is the reference point most cost-comparison threads on the sub now cite.

Claude Opus 4.7 landed on April 16, 2026, and after the first 48 hours on X and Reddit the verdict is net-positive but heavily qualified. Power users are calling it state-of-the-art for agentic coding, long refactors, and the viral new Claude Design tool. The loudest complaints cluster around runaway token burn (roughly 1.5-3x more expensive in practice than 4.6), an “ambiguity tax” where the model no longer silently rescues vague prompts, and confidently broken output on marathon runs. Users who prompt like they are writing a spec are getting enormous leverage out of it. Users who prompt the way they used to prompt 4.6 are burning through their usage caps before lunch.
